IMPROVEMENT IN LAND-ROLLERS.

Specification forming part of Letters Patent No. 179,599. dated July 4,1876; application filed May 8, 1876.

To all whom it may concern Be it known that I, WILLIAM B. PARSONS, ofNunda Station, in the county of Livingston and State of New York, haveinvented certain Improvements in Land-Rollers, of which the following isa specification My invention consists of certain improvements in theconstruction of field -rollers, as hereinafter more fully described.

Figure 1 is a top plan view, and Figs. 2, 3, and 4 are views of portionsshown in detail.

In constructing a roller on my plan 1 provide three rollers, A, whichmay be of wood or metal, as preferred, the two rear rollers be: ing ofuniform size, while the front one is of less diameter, as represented inFig. 1.

The front roller is mounted in a metallic frame, B, the form of which isclearly shown in Fig. 4. It consists of a cross bar, having pendent armsb, at each end, to'which is secured the axis or journal of the roller,with two vertically projecting cars, a, at its front end, for attachingthe tongue T bya bolt, 0, as shown in Fig. 1. It also has a semicircularbar or plate, 0, projecting from its rear side, which, for strengtheningit, is connected by a bar, I, to the main plate, though this may beomitted, if desired.

The front roller, being secured in this frame B, is connected to the tworear rolls by a bar,

E, as shown in Fig. 1, and at its front end this barE has secured to itsunder face a plate, C, which is shown detached in Fig. 3. This plate 0,as there shown, is made with a central hole for the pivot-bolt D ofplate B. It also has four vertical lips or lugs, e, by which it is heldsecurely in place on the bar E, as shown. In addition to these it isalso provided with two other vertical ears or lugs, d, which have holesin them for attaching the ends of brace-rods I, as shown in Fig. 1.

To the rear end of the bar E I secure a metallic plate, G, constructedas shown in Fig. 2. This plate is castwitbverlically-projecting ribs h,thus forniing on its upper face a recess of proper size to permit thebar E to fit in, and to which it is secured by one or more bolts. Thisplate G is also provided at each side with two.downwardlyprojectingears, a, between which, by rods or bolts m, are pivoted the journals Pof the rear rollers, one on each side, as shown in Figs. 1 and 2. Thesejournals P are each constructed with a flat plate at their inner ends,on which, as shown in Fig. 2, are two cars or lugs, 1', through whichthe bolt m passes, as well as through the cars a of plate G, thusforming hinge-joints, so that each of the rear rollers is free to riseor fall at its outer end, to accommodate itself to the inequalities ofthe ground.

The journals P are made in the form of round rods, of such a length asto extend eutirely through the rollers lengthwise, and project a shortdistance beyond; and on their projecting ends I slip the end of a bracerod, I, tormed, as shown in Fig. 1, and secure it, with the rollerthereon, by a nut or other suitable meansthis rod I having its front endhooked into the ear d of plate 0, as shown in Fig. 1. thus bracing thejournal P and preventing undue strain on the joints where they arehinged to the plate G, and at the same time permitting a free movementof the parts, as described.

By this method of constructing the metal portions B, G, and G, they canbe cast complete, with the exception of the holes for the bolts, and thejournals P may also be cast complete; or, if preferred, the roundportion which forms the axis for the rollers maybe made of wrought-iron,and may have the head, with its ears 1", cast on the wrought part,-oritmay be secured thereto by bolts or rivets, as may he preferred. Theentire frame, with the exception of the bar E, is thus made of metal,and in a manner which renders it exceedingly simple and cheap toconstruct, and is, moreover, very durable.

It is obvious that, if desired, a seat for the driver may be mountedon-thc bar E, or a box may be secured thereon for adding weight, whendesired.

Having thus described my invention, what I claim is l. The plate orframe B, provided with the segment 0, the pendent arms I) for securingthe roller, and the ears 0, for securing the tongue, constructedsubstantially as shown and described.

2. The plate 0, with the perforated ears (I, for hinging the brace rodsI, and lugs e, for holding it in place on the bar E, substantially asdescribed.

3. The plate G, provided with the ears 'n in rigid brace-rods I, one endof said rods being combination with the roller -j0urnals P, prosecuredto the outer ends ofsaid journals, and vided with the ears 1", bothconstructed and their other ends being hinged to the frame in arrangedto operate substantially as shown front, substantially as shown anddescribed. and described.

4. Thejournals P P, hinged so as to perinit Witnesses: the rollers tomove in a vertical plane at their GEO. W. DAGGETT, outer ends, incombination with the angular D. P. OARTWRIGHT.
